Cost-Methods {antitrust} | R Documentation |
For Auction2ndCap, calcMC calculates (constant) marginal cost for each product. For those classes that do not require prices, returns a length-k vector of NAs when prices are not supplied.
For Bertrand, calcMC computes either pre- or post-merger marginal costs. Marginal costs are assumed to be constant. Post-merger marginal costs are equal to pre-merger marginal costs multiplied by 1+‘mcDelta’, a length-k vector of marginal cost changes. ‘mcDelta’ will typically be between 0 and 1.
For Auction2ndLogit, calcMC computes constant marginal costs impied by the model.
For Cournot, calcMC calculates marginal cost for each product.
calcdMC computes the derivative of either pre- or post-merger marginal costs. The derivative of Marginal costs is assumed to be constant. Post-merger marginal costs are equal to pre-merger marginal costs multiplied by 1+‘mcDelta’, a length-k vector of marginal cost changes. ‘mcDelta’ will typically be between 0 and 1.
calcVC computes either pre- or post-merger variable costs. Variable costs are assumed to be quadratic by default. Post-merger variable costs are equal to pre-merger variable costs multiplied by 1+‘mcDelta’, a length-k vector of marginal cost changes. ‘mcDelta’ will typically be between 0 and 1.

object |
An instance of the respective class (see description for the classes) |
preMerger |
If TRUE, the pre-merger ownership structure is used. If FALSE, the post-merger ownership structure is used. Default is TRUE. |
t |
The capacity profile of each supplier. Default is ‘preMerger’ capacities. |
exAnte |
If ‘exAnte’ equals TRUE then the ex ante expected result for each firm is produced, while FALSE produces the expected result conditional on each firm winning the auction. Default is FALSE. |
